Abstract: A high frequency compression driver is disclosed in which the driver assembly is secured by two threaded studs. The studs not only hold the cover, magnet assembly and horn together, but also play a vital role in ensuring that the various elements of the assembly do not shift with respect to each other. The studs also serve as a basis for centering the voice coil precisely between the poles of the driver magnet. Although the magnet assembly is manufactured with ordinary machine tolerances, the diaphragm and voice coil are centered through the use of two precisely machined fixtures. The cover of the assembly acts as an effective heat sink for the diaphragm to keep its temperature low and improve the reliability of the device. The diaphragm itself is manufactured at low cost, is replaceable and is given structural integrity by the cover and the pole ring.
